Apparently the groundwater is being depleted around the Colorado River Basin, and that doesn't really replenish very fast even if there is rain.

In the past nine years, the basin — which covers Wyoming, Colorado, Utah, New Mexico, Nevada, Arizona and California — has lost about 65 cubic kilometers of fresh water, nearly double the volume of the country’s largest reservoir, Lake Mead. That figure surprised the study’s authors, who used data from a NASA weather satellite to investigate groundwater supplies.
